Since the mid-term exam is around the corner, I do start to read the book very carefully instead of just looking it over. For some parts of the book, I just feel that the way that author and editor adopts to write the book just complicates things that are not complicated. In addtion, I have to admit that I may not be good at reading, coz sometimes, I just can not figure out what authors really want to focus in one chapter without referring to powerpoints. After I communicate with other students, maybe it is not just me.
